Answer:
Here are my answers
hope this helps
Step-by-step explanation:
1. isosceles triangle
2. 3x + 15 = 90 x = 25
x + 25 = 90 x = 65
x + 55 = 90 x = 35
3. The size for DAB is 84
My reasoning is I went from one angle to another by subtracting 180 from my answers. For example angle 132 is supplementary to the missing angle next to it. I subtract 180 from 132 and get 48. That already solves the 2 equivalent angles in the triangle so I have 48+48+x = 180 because a full triangle equals 180. I get x = 84 then I do the same thing I did with angle 132. Angle 84 is supplementary to the missing angle next to it. I subtract 84 from 180 and get 96 then go diagonal from angle C (which is 96) to angle A. Those are supplementary so I subtract 96 from 180 and get 84.

Answer:
-9=-9 or just 1
Step-by-step explanation:
Answer:
The Tip amount is $ 9
Step-by-step explanation:
Given as :
The total dinner bill = $ 61.31
Rounding the bill to nearest ten dollars
The value of bill after rounding it to ten dollars = $ 60
Now The percentage of tips = 15% of dinner bill
So, The amount given as tip = 15% × $ 60
Or, The amount given as tip = $ 9
Hence The Tip amount is $ 9 Answer
Answer:
Therefore,
Step-by-step explanation:
Given:
In ΔABC, BC=4 cm,
angle b=angle c, and
angle a=20°
To Find:;
AC = ?
Solution:
Triangle sum property:
In a Triangle sum of the measures of all the angles of a triangle is 180°.
We know in a Triangle Sine Rule Says that,
In Δ ABC,
substituting the given values we get
Therefore,
